A mixed collection that goes beyond just Killer Sudoku. This book contains multiple types of puzzles - a variety of Killer Sudoku formats alongside other Sudoku variants, creating a diverse solving experience where you switch between different rule sets throughout the book.
DJAPE describes it as "the first of its kind" - a collection designed to showcase the breadth of what Sudoku variants can offer, rather than focusing on just one format. Each puzzle type is explained with rules and examples.
For solvers who enjoy variety and want to explore multiple formats without committing to a dedicated book for each one.
6 x 9 inch format. All solutions included. From DJAPE - 250+ puzzle books, PhD in Computer Science, Washington Post since 2006.
